Nichia to Start Sample Shipments of Green Laser
Green laser diode claimed to have a lifetime of 10,000 hours
Nichia which has succeeded in developing a green GaN-based laser diode, will start shipment of samples from August 2010. The firm claims that the diodes have an estimated lifetime of 10,000 hours under 50mW in continuous-wave operation at a temperature of 60°C.
The green semiconductor laser diode has a number of advantages over conventional light sources. In the case of pico projectors, these include small power consumption and volume, high efficiency, and low cost.
Cree and Philips Link up in LED Patent Agreement
The two firms have signed a worldwide patent cross-license agreement designed to further accelerate the growth of the LED lighting market.
Cree and Philips both hold broad and substantial optoelectronic patent portfolios which are important to their respective businesses. The comprehensive agreement covers patents from both parties in the fields of blue LED chip technology, white LEDs and phosphors (including remote phosphors), control systems, LED luminaires and lamps as well as LED backlighting of liquid crystal displays (LCDs) and patents in the Philips LED Luminaire Licensing Program.
“This agreement demonstrates the breadth and depth of both companies’ intellectual property, as well as the fundamental nature and value these patents bring to the market,” said Chuck Swoboda, Cree chairman and CEO. “It also signals both companies’ commitment to growing the LED market while respecting the value and importance of international intellectual property laws.”
“Philips and Cree have significantly invested in innovation in LED lighting solutions. The wide- ranging IP portfolios of the respective companies reflect the outcome of this effort,” said Rudy Provoost, CEO of Philips Lighting. “We wish to see
China SiC Industry is On the Up and Up
Yicheng has invested in the photovoltaic-based silicon carbide (SiC) powder Phase II and is now the world’s largest manufacturer of silicon carbide fine powder for the photovoltaic industry
Reportlinker has published a summary of the ‘China Silicon Carbide Industry Report, 2009-2010.’
China is the leading producer and consumer of silicon carbide, and its output in 2009 reached 535 kilotons or so, occupying 56.3% of the global total and ranking the first worldwide.
The Chinese SiC industry characterizes large output but lack of competitiveness. Despite the sufficient supply of output, most of China-made SiC products are low-end and preliminarily processed. However, certain demand-supply gaps exist in the refined and deep-processed products, which bring in greater revenue.
The surge in demand for products requiring sophisticated manufacturing processes like those used in the production of silicon carbide crystals is however far too great for China to cope with, even internally. In fact, in 2009 alone, China imported 1.3 kilotons of silicon carbide to make up for the domestic market deficiency.
In spite of some opportunities brought by the upgrading of product structure and the extension of downstream demand, the development of the silicon carbide industry, which is featured by high energy consumption and pollution, is exposed to hindrances from the influence of energy shortages and national energy conservation policies.
In particular, the examination and approval of new projects is restricted, and relevant preferential policies such as low electricity prices have already been discontinued. Consequently, the future development of China’s silicon carbide industry faces many uncertainties.
The report focuses on the following factors in the August/September 2010

the accelerated adoption of LED lighting, and are therefore delighted that Cree will be joining our LED Luminaire Licensing Program.”
